Hypoxemia

Hypoxemia is a condition in which there is a decrease in the concentration of oxygen in the arterial blood. This leads to insufficient oxygen supply to tissues and organs.

Clinically, hypoxemia is manifested by the development of cyanosis - a bluish coloration of the skin and mucous membranes. There are central and peripheral cyanosis.

Central cyanosis occurs when the partial pressure of oxygen in arterial blood decreases to less than 60 mm Hg. (8 kPa). In this case, cyanosis of the skin and mucous membranes is observed on the face, lips, and tongue.

Peripheral cyanosis is characterized by cyanosis only in the peripheral parts of the body (hands, feet) and occurs with a milder degree of hypoxemia.

Thus, the development of cyanosis indicates a decrease in oxygen content in arterial blood and is an important diagnostic sign of hypoxemia. With severe hypoxemia, respiratory failure develops, requiring urgent therapeutic measures.

Hypoxemia Hypoxaemia, or decreased oxygen content in the blood, is one of the most common acid-base balance disorders in the body. It can occur for a variety of reasons, including lung disease, cardiovascular disease, anemia and other conditions.

Hypoxemia can present with a variety of symptoms, such as fatigue, shortness of breath, dizziness, headache and disturbances of consciousness. In more severe forms of hypoxemia, respiratory failure may develop, which can be fatal.

One of the most important indicators of the presence of hypoxemia is the measurement of blood oxygen levels (SpO2). Normally, SpO2 should be at least 95%. When oxygen levels drop below this value, hypoxia develops, which can lead to various complications.

To treat hypoxemia, it is necessary to diagnose and determine the cause of its occurrence. Depending on the cause, various treatments may be prescribed, such as oxygen therapy, medication, and surgery.

Overall, hypoxemia is a serious condition that can lead to serious complications if not treated promptly. Therefore, it is important to monitor your health and consult a doctor when the first symptoms appear.

Hypoxemia (from the ancient Greek hypo - low, small and ὀξύς - sour), also hyperoxia - a decrease in the concentration of oxygen in the inhaled air or in the alveolar air. The term “hypoxia” usually refers to a condition in which the oxygen content in the atmosphere is less than 20% by volume; the norm for a healthy adult male is from 16-18% to 23% by volume. In the alveoli of the lungs of a person under normal conditions at sea level, the oxygen content is about 18%, i.e., hypoxia occurs when the oxygen content in the alveolar gases falls below this value. Based on the severity of oxygen deficiency, hypoxia can be classified as mild, moderate, severe and severe. A severe form of hypoxia is potentially fatal to the body and is the main cause of mortality during asphyxia or suffocation, since tissues require oxygen at least 90 milligrams per minute. Insufficient oxygen can be caused by various factors, including insufficient coagulation of oxygen carriers in the lungs, interfering with gas exchange between
